The fuse says something like "right rear tail light" or something about the rear tail lights. I had this happen to my car too. Turns out I was an idiot and didn't cover some of the non-hooked up wires and they shorted out the dash and running lights.
Go to
www.installdr.com to see how the factory and aftermarket radio harnesses match up. This really helped me in making sure that I had wired all the wires up correctly.
